I have used the Wii browser for over 800 hours... though I use it much less recently.
I also regularly use the Everybody votes channel.... and have spent a lot of time on the Nintendo and shop channel, but that is not really for entertainment as such (well it is in a way) I collect the data weekly for DKII to figure out Wiiware and VC sales.
I have on occasion (when I needed it) used the weather channel too... I have spent time on the news channel to see what it was like, but I don't find it useful and won't unless there will be a filter added in future so I can look at gaming news specifically.
I also use it to send messages, but not so much anymore because I am turning the WFC24 off to save electricity (and thus money)
